To all 'gvhom it ma concern:

Be ltkIlOWll 't at I, JACOB E..DAVIS, a

citizen of the United States, residing at Ironton, in the countyof Lawrence and State of Ohio, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

The .primar object" of the present invention is to pro uce a gas burner which is especially adapted to consume natural gas and-render its application to furnaces practicable, to which end, one feature of the invention resides in providing a plurality of gas and air mixing tubes in association with a specially constructed heat deflecting structure which, when applied to a furnace, will enable natural gas to be practicably used as fuel.

Another object of the invention is to provide a novel and economical construction ofburner and ;to further construct the heat deflecting structure in a manner to render it especially adaptable for use in connection with this particular construction of burner.

A further object of the invention is to producea as burner and heat deflecting structure w ich may be readily applied to a conventional type of furnace by applying the same to the fire-box of the furnace 4 reference to the accompanying drawings,

through the door leading therein. With these and further objects in view, the invention will be further described with and the points of novelty thereof set forth in the subjoined claims. I

invention will be first described with reference to the'preferred embodiment illus- Speclflcation of Letter: Intent.

trated in Figs. 1 and 2, in which 1, represents the heat deflecting structure which, according to the preferred form of the present invention preferably comprises a substantially cylindrical or round hollow bod preferably constructed of fire brick. n

order that it may act to produce the best result's, it preferably comprises a shell-having a thickened base 2, an outwardly flaring top portion 3, and a vertical wall 4,

tapering on its inside toward the outwardly flaring top portion 3', the outer wall, howeing preferably perpendicular. The

such means as the metal cover 5 and the metal bottom closure 6. The burner which is associated with the shell preferably comprises air and gas mixing tubes constructed to surround the perpendicular wall of the shell and disposed in sucha manner as to enable the flame to play against the under side of the outwardly flaring top portion 3,which portion will act to retard the flame and deflect the flame against the wall of the fire chamber of the furnace. In actual practice,

.- these tubes will be placed a suflicient distance from the furnace wall to enable a current of air to be passed from beneath up through this space where it will be mixed with the flame. As the inner circle formed by the shell is air-tight, all the air passin through the furnace will be forced into an around the flame. By this method the combustion may be brought to a veryhigh state of completion, and all the heat units of the gas will be utilized and discharged against the wall of the fire chamber. Furthermore, it is to be noted that the heating of the air is begun at the bottom of the fire chamber from where it "is deflected on to the upper portion of the fire chamber. The

particular construction of the tubes pre'ferably comprises a manifold pipe 7 which is adapted to have a double connection to suitable gas supply pipes. This manifold pipe 7 is provided' with a multiplicity of equally spaced openings '8 in its top, and directly over each opening is positioned a tube- 9. Steel bands, such as 10, are provided, preferably on both sides of the tubes and support the same nearotheir top and bottom by being electrically welded thereto. In order thatthe manifold pipe 7 may be securely held in place, a series of straps 11 are employed, which are looped under the pipe and clamped thereto by a bolt or rivet 12 with the respective ends of the straps fixed to the steel bands 10 supporting the tubes. With this construction of burner, a rigid circle is made surrounding the shell of the heat absorbing and deflecting structure. In order that the burner may be readily applied to the furnace through the door leading into the fire chamber, the shell 1 and the burner are constructed in half section,'but should it be desired, they could be constructed in quarter sections, or even smaller sections. In this respect, the burners may be joinedtogether by providing a union 13 for connecting the ends of the confrontin sections of the manifold pipe 7 For furnaces having a long fire box or chamber, the burners and the heat deflecting structure will be so designed as to conveniently fit therein.

The embodiment of the invention illustrated in Figs. 3 to 5 inclusive illustrates a square construction of burners and heat and deflecting structure.

sections. The embodiment shown in Fig. 6 illustrates a section of a much smaller heat absorbing and deflecting structure which would be applicable to small furnaces or even heating stoves. Fig. 7 illustrates a somewhat diiferent manner of clamping the strap 11 to the servicepipe, wherein the bolt instead of passing through the pipe ,is shown as clampin the strap to the pipe by a bolt positione immediately above the pipe, at suitable sleeve 14: being employed.
